hrlcation of vehicle springs.

Mo'st present day automobiles have leaf springs whicmare provided with metal covers enclosing the leaves of said spring and adapted to be packed W rease, inorder-thatsaid leaves will operate Withoutfriction or. noise- Q the. no zle of a grease gunso that greasetm r e domed, throuehv .saidtool into-the cover-fife! he P pose stated.

The object of the present-invention is to provide :a-novel fitting adapted to be permanently associa ed w th the lubrication .openingofeach spring cover, which fitting is provided with a headed male stud with which th female coupling of a conventional grease gun is adapted to be deopening of each spring cover to remain there throughout the life of the car and thus facilitate efiicient and thorough greasing of the springs throughout that protracted period.

A further object'of the invention is to provide a simple, economical and cheap fitting for the purpose stated and one which may be depended upon to retain its position on the cover and to be available" at all times for the carrying out of its functions. j

Speaking generally, the fitting of this invention comprises a rigid channel section provided centrally with a''l'iole in which a stud is permanently secured. One end of the stud projects between the flanges of the section and constitutes a head shaped yoke' embracing the cover with the ends of the yoke passing through holes near the ends of the channel section and threaded to receive bolts for the purpose of binding the channel section firmly in place on the cover.

'Features .-orthe invention, other than those adve'rted to,-will be apparent from the hereinafter V detailed. description-and appended claims; when readiwin" ?conjunction with: the accompanyin drawing.

The accompanying drawing illustrates one practical embodiment of the invention, but the construction therein shown is to be understood as illustrative, only; and not as defining the limits of the invention.

Figure Us a perspective view showing the fixture of this inventionv as viewed to show the top portion thereof.

Figure 2 is a like view but showing theabottom portion thereof. I Figure 3 is a longitudinal section of a spring and 'its: cover with the fixture of this invention attached, the section being taken on the -line.3-.3

of Figure 4.- 20

Figure 4 isa transverse section on the line. 4-4 of Figure 3 with the yoke in elevation.

"Referringto the drawings L designates the leaves of an automobile spring enclosed within a conventional spring cover C. The cover is provided in its bottom with a lubricating hole H, adjacent which the cover is outwardly domed as indicated at D.

The fixture of this invention comprises an elongated channel section having a web 2 and flanges 3. This channel section is somewhat longer than the overall width of th spring and its cover, as shown in Figure 4, and it is of sulficient weight to be rigid and non-bendable, so that it will hold its shape during and after attachment to the spring. The center of the channel section is provided with a hole 4 and said section has elongated holes 5 near its opposite ends, said latter holes being beyond the lateral edges of the spring cover C.

Within the central hole 4 is rigidly afiixed a stud 6. One end of this stud is in the form of a plug 1 adapted to extend through the hole H with a flange 8 at a base of the plug to bear against the outer surface of the domed portion D. If desired a soft washer may be interposed between these parts although this is not essential. The other end of the stud is in the form of a connection head 9, shaped to be received into the female connection nozzle of a grease gun. The stud has a central passage l0 through which grease may be passed from the grease gun into the interior of the cover.

The stud is secured in cooperative relation with the cover by means of an inverted U-shaped yoke I l which extends across the top of the cover and downwardly along the sides therethrough,

When each of the spring covers of -acar are; equipped with fixtures embodying the present in-.-,ivention, the lubrication of the springs becomes The necessity of" a simple and easy matter.

manually holding the grease gunincooperative '1 relation with the spring no longer prevails and adequate pressure maybe applied to insure thorough packing of the spring cover with grease.

The device of this invention is simple, very economical to manufacture and it may be installed with ease and very quickly. It fills a long felt want and it makes it possible to properly grease springs quickly and without arduous labor.

In the foregoing description and in the drawing, the passage [0 through the stud through which the grease in introduced into the casing is shown as unencumbered. I may, however,

provide this passage with a check valve which will permit grease to enter the spring cover but preclude its exit through the passage when the cover has been filled and the grease gun removed.

The foregoing detailed description sets forth the invention in its preferred practical form, but the invention is to be understood as fullycommensurate with the appended claims.

Having thus fully described the invention what Patent is: V

1. A grease fitting for automobile springs en- I claim as new and desire to secure by Letters" 4 closed in metal spring covers provided with a lubrication hole comprising: a channel section the web of which is provided with a central hole in which is mounted a stud having a grease passage therethrough, one end of the stud projecting beyond one face of the web to extend into the lubrication hole of thesmjin cov r and t e other end. of the stud; having a: head to engage with a grease gun, and a U shaped yoke to extend over the spring and downwardly along the sides thereof and through holes in the ends of 5 thewebof'the channel section, the ends of said I yoke being threaded, and nuts screwed on to the yoke for clamping the springcover and spring tightly between the channel section and the yoke 'Ito maintainuthe plug of the stud firmly seated in the lubrication hole of the cover.

2. A fixture as claimed in claiml, wherein the end of the stud which engages with the grease gunis a male connector adapted for temporary interlocking relation with the nozzle of a grease VITO FRESOLONE, JR.
